Shoulder arthritis is a clinical condition in which the joint that connects the ball of the arm bone (humeral head) to the shoulder blade socket (glenoid) has damaged or worn out cartilage. Normally the ends of the bone are covered with hyaline articular cartilage , a surface so smooth that the friction at the joint is less than that of an ice ...
The risk of osteoarthritis increases with aging, history of joint injury, or family history of osteoarthritis. [18] However exercise, including running in the absence of injury, has not been found to increase the risk of knee osteoarthritis. [19] [20] Nor has cracking one's knuckles been found to play a role. [21]
Several factors contribute to the development of arthritis, differing on the type of arthritis. [2] [6] Osteoarthritis occurs from damage to joint cartilage from prior injury or long-term wear-and-tear, resulting in bone-to-bone contact and grinding. [6] The resulting arthritis can occur over years, or be worsened by further injury or infection ...

The main risk factors for osteoarthritis are age [2] [3] and body mass index, [4] [3] as such, OA is predominantly considered a disease of aging. [5] [6] As the body ages, catabolic factors begin to predominate over anabolic factors resulting in a reduction of extracellular matrix gene expression [7] and reduced cellularity [8] [7] in articular ...
Experts questioned 3,357 retired Olympians aged around 45 on injuries and the health of their bones, joints, muscles and spine. Elite sportspeople at higher risk of osteoarthritis, research shows ...
Loss of bone minerals means a decline in bone mass, thus bones will be weaker in some areas resulting in individuals to be at risk of minor or major falls that could be detrimental. It is known that exercise can allow for stronger bones in order to slow down bone loss in individuals as muscle mass can be built to support and reduce the risks of ...
The capsule is a soft tissue envelope that encircles the glenohumeral joint. It is lined by a thin, smooth synovial membrane. [citation needed] The bones of the shoulder are held in place by muscles, tendons, and ligaments. Tendons are tough cords of tissue that attach the shoulder muscles to bone and assist the muscles in moving the shoulder.
